HARRY S. HART, OF CHICAGO,

HOPPER-CAR ARRANGEMENT;

Application filed August 4, 192 1 $erial l To.48 9,69;8.

To all whom it may concern: I

Be it known that I, HARRY S. 'HART, a citizen of the United States, residing at rangements, of which the following is a specification. l I

This invention relates to a new and improved hopper car arrangement, and more doors for such cars.

car uses, it is highlyv desirable to. provide dumping doors adapted selectively to dump the material between therails orto either. a side of the rails, and to avoidflooding the.

rails.

provide a door arrangement for such cars side the rails. It is a furtherobjectto provide a construction of this character which is simple in design and composed of but few and rugged parts It is an additional object to provide the doors so associatedwith.

the car body as to give amaximum of carryingcapacity.

Other and further objects will appear as the description proceeds. I

In the embodiment of my invention selected for illustration, I have shown a. car having theusual underframe composed of center sills and cross sills, the car being provided between the trucks'with a'longitudinal hopper'having its apex-beneath the center sill.

- As my invention relates particiilarly to thishopper arrangement, I have not illus trated or described the-constructionof the car at the ends over the trucks: It will be 'understood,however,- that this maybe the well known construction of the Hart convertible car. i,

I have illustrated a preferred embodi-i accompanying ment ofim-y invention in the drawings in which Flgure 1 is atransverse section of a'hop- 'per' car--provided with the door construction ofthe present invention, the doors being closed. Q V A Figure 2-1sua fragmentary view. similar to Figure 1 and showing thercenter. dump doors open. I Figure?) is a viewnsimilar .to Figure 2v showing the, g t lat ral dump door open,

It is an object of the present invention to R f r ng t th ra ings th iar compri es. t n t e Sides. cen e l s andcross frames 7. The lower portions 8' of the cross frames are formed ,in'the'sliape o ad ard y. d r t V- I At e t ersi the car is provided withinwardly and downwardly sloping fixed floor sections 9.; The I longitudinally extending framemembers 10" e ecured interme ate. the l gs o the pi t ons'8, eseim m qers 10, as shown. being of Lbeambross, section. The outwardly th outerface o 'f th amem ers; l0- 7 doers 1 are c nnec d byl ha sz i t P erat-ing shafts 14:,wh ich shafts mayberotated by any desired, mechanism 1(not shown).

The inwardly I opening-.' center;

. opening doors?11 arefpivoted at 12. against In connection with a number of hopper dump doors 1 5 are pivoted at 1"6adjacent the inner face. of the members vThe doors 15. upon opposite, sidesfof the car meet at. 17, at the apex ofsthel vnemberi8. The I center door operating shaft 18 isl'carried by, the members 8 above the apex, of, the V and' below the center sills 6, This shaft, 18

carries; the gear wheel 19,, wh ichis in mesh with the worm gearv 2O uponthe laterally extending shaft 21",. his shaft being proyided with operating hand, wheels 22. Asbest shown iin Figure 2, the shaft :18 is, also provided with the operatinggarms 28cand24, these arms being separated by an anglex'of approximately ninety degrees '.The arm 23 is connected by link 25, t themighthand door 15. The arm 24 is, similarly connected by a link 26 to thele'ft hand: doordl 5f The links 26, as shown, are arcuate inheontou rgin order that they maypartiallyenoircle[the as shown in Figures 1 and/3, :1

In t pe a of! my du p door,

rangement the center doorsfor gdumping .be-

tweentherails are operatedby rotating the shaft. 18- when thev center doors 'arejclosed,

shaft2l, by means of the handgwheels-22,

this rotation being transmittedto the shaft 1.8 by. the-worm; gear 20 and gear wheel 19.

:They arms 23 and 'and links 25 nd-26 are thus rotated from the position ofFigure 1;.tol that: o-fFigure -2. l\ Iater ial ihpthe car then passes by grayity-out. through the two doors '15, these doors servingto; direct it between the rails. The side doors 11 are held in their-closed position and serve, tq aid in guiding. the material tov the centenbpening, The carw-ill cleanly dump ,all materialwill completelyrpassout, Fe laeal ame to. am ss e part of the material carrying hopper so that the greater part of the material is guided through the opening by the fixed sides and by the doors upon the opposite side of the car. To close the door the shaft 14 is rotated in the reverse direction.

It will be seen that my construction, as shown and described, provides a hopper car carrying a maximum amount of load and in which the door construction is slmple and rugged and may be readily operated, to deposit the material either between the rails or outside the rails and without flooding them.

What I claim is'.

1. Ina dump car, a bottom comprising inwardly sloping side portions, each said side portion comprising outwardly opening doors for side dumping and inwardly opening doors for center dumping, and means for operating said doors.

2. In a dump car, a bottom comprising inwardly sloping side portions, each said side portion comprising outwardly opening doors.

for side dumping and inwardly opening doors for center dumping, said outwardly and inwardly opening doors being independent of eachothe'r when closed, forming, to-

gether, continuous inwardly sloping side surfaces.

3. Ina dump car, abottom comprising in-v wardly sloping side portions, each said side portion comprising outwardly ing doors for center dumping. said, outwardly and inwardly opening doors, when closed, forming, together, continuous 1n- I wardly slop ng side surfaces, theadjacent edges of said doors being pivotally con nected to the car.

{1. In a dump car, a bottom comprisingin wardly sloping side portions, each said, side? v portion comprising outwardly opening doors for side dumping and inwardly opening doors for center dumping, the outwardly opening doors, when closed,'serving to guide material through the inwardly openingdoors when the latter are opened. V

5. In a dump car, abottomcomprising in-" j' wardly sloping side portions, each said side portion comprising outwardly opening doors for sidedumping and inwardly open- "ing doors for center dumping, a longitudinally extending shaftadjacent the, inwardly openingdoors and links connecting said doors to the shaft whereby rotation of the portions, a longitudinally inwardly member secured V opening .doors for side dumpmg and inwardly open Of July, 1921.-

shaft in one direction closes both doors and in the opposite direction opens both doors, and means for operating the outwardly opening doors.

6. In a dump car, center sills, transverse frames having downwardly extending V- portions, a longitudinally extending frame member secured intermediate each leg of the \J', inwardly opening doors for center dumping pivoted adjacentthe innerfaces of the longitudinal frame members, and outwardly opening doors pivoted adjacent the outer faces of said members, and means for opelr ating said doors.

7. In a dump car, center-sills, transverse frames having downwardly extending V extending frame member secured intermediate each leg of the T V, inwardly opening doors for center dumping pivoted adjacent/the inner faces of the longitudinal frame members, and outwardly opening doors, pivoted adjacent the outer faces of said' members, said outwardly and opening doors, when closed. forming, together, continuous inwardly sloping side surfaces.

8. In a dump car, center sills, transverse frames having downwardly extending V portions, a longitudinally extending; frame intermediate each leg of the V, inwardly opening doors for center dumping pivoted adjacenttheinner surfacesot the longitudinal frame members, and outwardly opening doors, pivoted adi acent the outer faces of said members, the outwardly opening doors, when closed, serving to guide material through the doors when the latter are opened.

9. In a dump. car, center sills, transverse frames having downwardly extending V- portions, a longitudinally extending frame member secured intermediate each leg of the V, inwardly ing pivoted adjacent the innerfaces of" the longitudinal frame members, and outwardly opening doors pivoted adjacent the outer faces of, said members, a longitudinally extending shaft carried by'the transverse V-- frames adjacent the apexthereof andflinks connecting the shaft to the inwardly opening doors whereby rotation of the shaft in one direction closes both doors and in the opposite direction opens both "doors,- and" means for operating the outwardly opening doors. 1

10. A dump car havingits floor-between the trucks in the form of a longitudinallv extending hopper having its apex beneath thecenter line of the car, the sides of said hopper'comp'rising doors hinged at an intermediate point of the sides'to swing downwardly toward each other. I
